Located in the hills above the forest of Eu, overlooking the Bresle valley, the archaeological site Bois l’Abbé was discovered by accident when a road was created across the forest at the end of the 18th century.
Successive excavations took place during the 19th and 20th centuries. They allowed people to become aware of the importance of this site which was a Gallo-Roman town with its Basilica, its big sanctuary, its public squares, its houses, etc. In 2006, a dedicatory plaque was found and gave it its name: Briga.
Nowadays, excavation works take place all year round on this archaeological site. In summer, volunteers and archaeology lovers lend a strong hand to archaeologists. Guided tours are organised in July and August.
